Well Rehabilitation, pH, and pH Meters

Practitioners need to understand the chemistry of the well water they work with.

By Christopher S. Johnson, PG, CHg

The absence of codified procedures and standards for well rehabilitation requires those who conduct such projects to engage in sound science and technology. One of the more important components of our work is the thoughtful use and application of chemicals, and more specifically acids, in the prosecution of our efforts.

Acids are effective chemicals against mineral encrustation and biological fouling when properly applied by type, concentration, and volume. It goes without saying competent practitioners who use acids in the course of their practice know they need to understand the chemistry of the well water they work with.

However, acids are dangerous if not given full respect, handled carefully, mixed carefully, and all in the correct safety equipment.
